latch will engage the bottom ot the door so as to hold the same open(see Fig. 1). When the lever o is rocked counter clockwise the latch ais drawn back so as to release the door e, which will then fall to aclosed posit-ion as it is of greater weight than the noor c (see Fig.2).

To hold the floor c in the raised position shown in llig. 2, with thelatch 15 acting as a strut..

@n one end or" the bar w is mounted a tray .fr `for receiving the eggwhen the nest 7c resumes its normal or inclined position, because ot thehen jumping from the nest back onto the licor c. At the other end ot thebar `fw is an adjust-able counter weight y, which normally holds the barw in the position in whichit is shown in the full lines of Fig. 2.

When an egg rolls 0n the tray a its weight rocks the bar wcounter-clockwise to the position shown by the dotted lines ot Fig. 2,throwing the latch@L at such angle. that its notch no longer will engagewith the lip u of the bar w. 'lo insure that the depression of the barfw will throw the latch t out of engagement the former has mounted on ita linger 17 which functions to push the latch od the lip u.

While passing out of the housing the hen has automatically placed uponher a drop of pigment so that she may be recognized as a layer.

F or the latter purpose l provide mechanism comprising a lever-arm 2pivot-ally mounted upon a bracket 3 rigidly supported by the outer faceof the door e. lChe inner end ot the arm 2 carries a pivoted pendant rodor dauber l; on the other end ot the arm Q, is an adjustable weight 5tending to hold the arm as shown in Fig. 3.

A. container holding pigment 6 (see `Fig. Il) is placed in an opening inthe licor c, directly beneath the dauber 1, and a hinged cover 6',normally closes the open top of the container 6. An arm 6b connectingthe cover 6a with the lower end ot .the lever o, operates to remove thecover when the lever o is rocked counter-clockwise, and to replace itwhen the lever 0 is rocked in the opposite direction, (see Fig. 1). Thelever 0 and rod 6h are located at one side of the iioor c so as to clearthe latter.

A cord 7 is secured to the outer end ot the lever arm 2 and the otherend of the cord is tied to the frame member a2. qWhen the door e is inthe raised position, the cord 7 is slack as shown in Fig. 4l, but whenthe door is lowered7 the cord is taut and pulls the cuter end ot thelever-arm Qup, and thus causes the dauber 4 to dip into the pigment inthe container 6. `When the door e is a ain raised, a drop of pigmentwill be earned by the lower end ot the dauber aready to be depositedupon the baclr ot the hen as she leaves the housing.

The dauber i carries a weight 2O tending to hold it against a cleat 21fixed on the bottom ot the door e, and the dauber l works in a staple orguide 22.

lt-'is not desirable to have the dauber l drag pigment over the body ofthe hen, but only to deposit on her a drop of the pigment. To insurethis effect l provide means for instantly lifting the dauber 4- uponhaving touched the hen, such means being` arranged as follows:

A iiap 9 is pivotally pendent from the bracket 10 which is carried bythe door c. A catch 11 provided on the upper end ot' the flap 9 isadapted to engage with an arm 12, which is pivotally hung from the arm2. @n the lower end ot the arm 12, is pivoted a latch-bar 18 one end ofwhich engages with the catch 11 ot the liap 9; and from the other end ofwhich is pivotally hung a. triggerbar 19.

lhus when the hen passes through the door-way her body will come incontact with the iiap 9 and she will swing that outward into itsposition as shown in Fig. l. l'n so doing she will cause the catch 11 oithe ilap 9 to engage with the latch-bar 18 which resists tilting byreason ot the weight of the trigger-bar 19 suspended therefrom asmentioned, and hence the pressure of the catch 11 on the latch-bar 18will result in pulling the arm 12 downward and tilting the by releasingthe arm 12 and hence permitting the weight 5 to function to tilt the arm2 so as to litt the dauber 1.

Should it happen that the hen does/not Sti rise when 'feeling the touchof the dauber otally mounted on the member 111- and con- `trapped withinthe nest.

nected to the nest-arm lo? by a link 16, serves as a stop for the traywhen the latter drops to the position shown in dotted lines in Fig. 2.When the nest is again lowered by another hen, the lever 15 will berocked to the position shown in the full lines in Fig. 2, thuspermitting the arm w carrying said tray to drop still further and letthe egg roll off on the floor or into a box. The tray w is then liftedto its normal position by the counter-weight y.

I will now describe the cycle of operation of my device: Normally whennot in use, the parts of my device will be positioned as shown inFig. 1. It is to be noted that the door e is open, and a hen may freelyenter through the entrance of the housing. The hen so entering, willpass under the door e, and hop onto the nest c. Her weight will thencause thel nest to tilt downward' into a horizontal position, whereuponthe door-closing devices will operate to release the door e and permitit to close, and all parts will assume the positions shown in the fulllines of Fig. 2. The hen is now When she is ready to leave the nest 7c,she will hop onto the floor c. It she has not laid an egg, there will beno consequent operation of the parts, and she will remain trapped, andcan be released only by manually operating my device. If however, shehas laid anegg, the latter will roll onto the tray a: of the bar w,depressing the latter so as to disengage the latch t, and when the henthen jumps backonto the floor c her weight will cause the latter to tiltdown to a horizontal, position. The described mechanical connectionsbetween this floor and the door e, will then cause the latter to open,and thus permit the hen to walk out. However, as the hen passes throughthe entrance of the housing, her back will brush aga-inst the -lap 9,and thus bringing into action the dauber 4 will deposit a drop ofmarking liquid on the back of the hen.

I claim:
